MECHANISM FOR TRANSFERRING WARE FROM LEERS.

To all whom it may concern;

Be it known that I, LEONARD D. SoUBrER, a citizen of the United States, residing at Toledo, in the county of 'Lucas and State of Ohio, have invented new and useful Ims provem'ents in Mechanism for Transferring Ware from Leers, of which the following is a specification.

My invention relates to leers for annealing glass articles, 0 handling the articles at the delivery end of the leer. More particularly, the invention relates to automatic means for transferring bottles or other articles from the leer pans on which they are held in inverted position, placing them in upright position on a hor1- zontal conveyor and carrying them away from the leer.

An object of the invention is to provlde a practical form of mechanism for automatically receiving and conveying the ware from the leer to selecting tables or a convement place for inspecting, sorting and packing the ware. In this manner there is avolded the necessity of selectors working at the end of the leer under the crowded, overheated and inconvenient conditions which usually prevail with present methods, these adverse conditions being especially pronounced where the output of the leer is large.

Other objects of the invention will appear hereinafter.

In the accompanying drawings:

Figure 1 is an elevation view of the delivcry and of the leer, parts be ng broken away.

Figure 2 is a side elevation of the same, with mechanism for transferring the bottles from a leer pan to a horizontal conveyor.

Fi re 7 is a detail view of the mechanism for ischarging the bottles from the leer pans and transferring the pans from the: leer to a conveyor outside the leer.

The present invention is herein shown in connection with a leer of the type disclosed in the patent to Michael J. Owens, Number 1,117,433, November 17, 1914. In this and automatic mechanism for rotation by means of reciprocatin type of leer the leer conveyor comprises a serles .of pans or ware holders which travel through the leer from thereceiving to the.

discharge end of the leer, each pan extend ing transversely of the leer and providedwith a row of sockets or holes to support bottles or the like in an upright inverted position. Each said pan when it reaches the discharge end of the leer, is automatically shifted in the direction of its length to a position at oneside of the leer, is advanced to a receiving position, receives av fresh sup ply of articles to be annealed and is returned to the receivin end of the leer. This general method 0 operation is carried out in connection with the present invention.

' Referring now to the accompanying draw-. mgs:

The leer pans or ver'sely of the leer and are placed side by side one in advanceof another, as indicated 1n Figure 2. Each said holder is provided with a row of sockets or holes 11 shaped to receive the necks of bottles 12 or other glass articles and hold them spaced apart in an upright inverted position. The leer pans 10 ad acent the discharge end of the leer are supported on beams or supporting bars 13 extending lengthwise of the leer. The pans are advanced step by step by means of shiftholders 10 extend transing supports or carriers 14 (Fig. 1) actuated by a cam 15 operating through a lever 16 and links 17. This operating mechanism may be of the usual or standard construc.

v izontal conveyor 42. This transfer mecha- 4 is an elevation vlew of the hor1-.

nism comprises a shaft'20-extending transvversely of the leer, arms 22 fixed to and ex tending radially from the shaft and holders 23 at the outer ends of said arms. Said holders may be in the form of angle bars shaped to receive and hold the leer pans 10. The transfer device, as shown, comprises three of said holders 23 equally spaced around the shaft 20 and arranged to be' brought successively in alignment with the leer pans.

The transfer device is given a step by step slide blocks 24 working in stationary guides 25 27 carried by said slide blocks.

and actuated by cams 26 on which run rolls I The cams 26 are fixed to a shaft 9 driven through .wormgearing 8. The motion of said slide blocks 24 is transmitted through levers 28 fulcrumed at 29 and connected through links'31'to rock arms 32 loose on"the shaft 20. Said arms 32 operate through a pawl and ratchet 33 to rotate the transfer device step by step. This operation is in timed relation to the step by step. feed of the leer pans, so as to pick up and transfer a leer pan and its ware after each advance of the leer pans in the leer.

Each operation of the transfer device causes a pair of holders 23 to pick up the other ware to stick in the leer pans, and in order to insure their release, a positive means is provided comprising a bar 36 carried by rock arms 37 on a rock shaft 38 having connection through links 39 with slide blocks 40 in the path of the levers 28.

When the levers 28 operate to transfer a leer pan to position b, the bar 36 through the connections just described, is swung down to the position shown in Figure 7 and in dotted lines in Figure 2, thereby striking and releasing fromthe leer pan any bottles which have not already been released, and

- also giving them a forward impulse or start down the platform 34.

The conveyor comprising the holders 35 and chains 18, is preferably given a step by step movement in timed relation to the movements of the transfer device, so that a holder 35 is always in position at the lower end of the platform 34 when required to receive the row of bottles discharged from the leer pan. This step-by-step movement is effected by means of a pawl and ratchet device 7 (Fig. 2) actuated by the lever 28 connected thereto through a link 6.

The holders 35 discharge the bottles on the horizontal conveyor 42.''- For this purpose, they are provided with lugs 43 pivoted to the conveyor chains, an are also provided with arms 44 carrying cam-engagmg rolls or studs 45 which/min on station ary cams 46 and 47. The cam 46,.is so shaped that it will guide the holder 35 and cause it to deposit the bottles "on the horizontal conveyor 42, as indicated in Figure 3. In this connection, it will be noted that, as shown in Figure 6, the bottoms of the Sometimes, howi ever, there is a. tendency for the bottles or articles from the leer pans.

bottles protrude beyond the edge of. the

- holder 35. This insures the-bottles being arrested by and pushed onto the conveyor. In order to prevent the bottles from being tipped over as they are placed on the con-' yeyor, a guard 48 is provided. This guard is adjustably mounted on stationary brackets 49 andis held in adjusted position by a set screw 50.

The horizontal conveyor 42 extends across the front end of the leer and for some distance beyond the leer at one side thereof, as shown in Figures 4 and 5, so that the bottles or other articles are carried to selector tables or within convenient reach ofthe selectors at the stations 52. The selectors seated at these stations may take the bottles from the conveyor and inspect them in the usual way, discarding the defective ware and packing the perfect ware. An inclined stationary guide 53 (Fig. 5) is arranged to guide the bottles from the edge to the center of the conveyor. Each row of bottles is carried by the conveyor to a position at one side of the leer before the next row of bottles is placed thereon. v

As each leer pan is moved from position a (Fig. 7) to position b, the'pan in advance thereof is at the same time moved from o.- sition b to a position 0. The holder 23 .by the time it reaches position a has been inverted, so that it permits the leer pan to drop therefrom and slide down an inclined I guideway 54 onto a conveyor 55. Figure 7 shows, in broken lines, the leer pan in suc- 'cessive positions assumed as it slides downthe incline 54. A guard 56 prevents the leer pans from dropping out of the holders 23 before they have reached the position 0. It will be noted that each leer pan during its transfer from position a to the conveyor 55, is given a complete rotation about, its own axis, so that it is again right side up when it reaches said conveyor. The pan is now' returned to position to receive a new supply of bottles and again introduced into the leer by mechanism such as disclosedin the Owens patent above referred to, or other approved mechanism, which need not be here described.

Modification may be resorted to within the spirit and scope of my invention.
